दो रेखाओं \(\frac{x+2}{3}=\frac{y-2}{5}=\frac{z+5}{7}\) तथा \(\frac{ x -1}{1}=\frac{ y -4}{4}=\frac{ z +4}{7}\) को अंतर्विष्ट करने वाले समतल की मूलबिन्दु से लम्बवत् दूरी है

  1. A \(11\sqrt 6 \)
  2. B \(11/\sqrt 6\)
  3. C \(11\)
  4. D \(6\sqrt {11} \)
Verified Solution

Answer & Solution

Correct Answer

(B) \(11/\sqrt 6\)

Step-by-step Solution

Detailed explanation

Equation of plane is \(\left| {\begin{array}{*{20}{c}} {x + 2}&{y - 2}&{z + 5}\\ 3&5&7\\ 1&4&7 \end{array}} \right| = 0\) \(\Rightarrow(x+2) 7-(y+2) 14+(z+5) 7=0\) \(\Rightarrow x-2 y+z+11=0\) The perpendicular distance from the origin to the plane is…
